XMPP

“work everywhere, don't need a phone number (at all, ever), and have free as in freedom clients and servers”

“nothing in XMPP is normal or comfortable. Everything has this weird particular flavor to it and more complexity than necessary.”

“writing an XMPP client is a full time job of solving weird problems that shouldn't exist in something better designed”

“the extension component model being difficult to write clients for, which is true but not really a fault of the protocol”

“Jabber/XMPP was used today to the satisfaction of everyone when I video-called my 90 years-old relative.”

“Some use cases like business chat actually can't have E2EE, and that'd probably be Jabber's foot in the door”

“XMPP has brilliant session management, it reconnects more seamlessly than many other protocols on mobile.”

“XMPP comes very close. You've got a healthy ecosystem of independent client and server implementers, and service providers to choose from.”

“We already have XMPP and Matrix, all that's required is for public institutions to use them.”

“I used xmpp as my primary communication tool through the whole thing and it worked ok on my first android phone”

“papercuts like these need to be solved before I can recommend it even to technically open-minded friends”

“From over a decade of using XMPP daily, this concern is more of philosophical nature than anything.”

“XMPP started out as a message routing protocol, with server-side history bolted on as an afterthought”

“XMPP kinda has a Plan 9 or Amiga type of vibe, cult following "ahead of its time", but never took off totally how people hoped”

“XMPP leans heavily on capability negotiation and service discovery which makes it straightforward to degrade gracefully when feature mismatches occur.”

“I have yet to find a client that can replace Telegram's client on both desktop and mobile.”

“I've used Jabber/XMPP for just over 15 years and while I've seen plenty of bullshit going on in various highly popular MUCs”

“XMPP lacks official support for something as basic as "I want to log in on a new device and see the old, encrypted messages"”

“XMPP has extremely simple and familiar "WhatsApp"-like clients, so there's really not much of a barrier to entry”

“Second best option is XMPP with various cobbled together XEPs but that has its own set of problems.”

“Anything without push notifications was a no-go, and in practice you usually didn't get those from an XMPP server.”

“XMPP enables someone with a network operator to apply wide, symmetrical configurations across a network”

“The best part about XMPP, or rather "protocol not service" as the OP discusses, is that you can go beyond the intended use case of it.”

“Well-known design issues causing message losses, fractioned ecosystem due to varying implementation of extensions”

“XMPP sounds like a success story of diversity, but the cost of that is that normies don't even know what it is.”

“I just think both need a modern UI that supports everything that Discord offers OOTB.”

“XMPP's biggest failure is that there is no client which is on advanced on most of it's compliance suites”

“If the answer to "it's confusing" is "there are apparently standardised sets", it sounds like it is, indeed, confusing”

“It does everything you need it to do, has done so since the 90s, and doesn't require any PII, ever.”

“has proven that it actually works, and has a reliable community behind it, with no VC-funded hype”

“xmpp has an impressive ecosystem and some incredible client implementations on a shoe string budget”

“XMPP was nice. Especially in the old times when Google Hangouts and Facebook Chat were also XMPP based.”

“Being able to talk to people on another service without needing an account there was a nice thing to have for a few months.”

“Being able to talk to people on another service without needing an account there was a nice thing to have”

“at least most XMPP extensions are designed to be backwards-compatible with clients that don't support them”

“But I really do wish we had doubled down on XMPP. It was nearly everywhere in the late-00’s early-10’s.”

“Federativity, voice calls, E2EE, direct and offline file exchange, no sms verification and other bs, max privacy and convenience.”

“It has all the guarantees you might desire from Signal without the hanging sword of Damocles hanging over your head.”

“Matrix and XMPP are excellent protocols for decentralisation, but their E2EE implementation leaves all kinds of metadata exposed”

“we now have E2E encrypted audio and video calls that run on software that's Free and federated”
